Very nice and singable. I really like the harmonic direction. The piece has a lot of character.
The vowel in “World” is such that an extended upward slur on it could be a bit painful to hear, depending on the congregation.
The accents in the word “darkness” don’t line up with the beats, which will make it a bit more awkward.
I think I like the chromatics, but am not quite sure I like how they resolve. Could they resolve into another key so that they sound more like a natural part of the progression than just a moment of color? I recognize that that could be hard to do.
Otherwise, I really like it!
